The ISC R-ALF™ Pulley is the latest innovation in Rescue, Confined Space working and Work Suspension Systems.
The R-ALF™ Pulley has an over-speed brake built in so that the Pulley will lock on and hold when a fall occurs. The load rated Becket Eye on the R-ALF™ means that it can be used in combination with Prussik Pulleys to create a 3 : 1 or 5 : 1 Mechanical Advantage System.
The R-ALF™ system locks in both directions and can be set up with almost any EN1891A 11 mm (7/16th) rope – the only practical limitation to ‘height of lift’ being rope stretch and/or weight kit. We recommend the 11 mm PMI® Hudson Classic Professional Rope https://pmirope.com/product/11-mm-ez-bend-pmi-hudson-classic-professional-rope/
The R-ALF™ can be used as part of a work suspension system either on tall structures or confined spaces. A user can easily lift/lower themselves off by using a Hand Ascender https://pmirope.com/product/isc-professional-hand-ascender-right-hand/ or short strop https://pmirope.com/product/heightec-protected-sling-60-cm/.
The unique design of the R-ALF™ (design patent applied for), means that an internal brake is not required and therefore it is capable of several thousand cycles and many arrests* (*minimum 12 monthly service intervals apply).
